Hard Bricked 4x

Hi,
I have a following problem with my Redmi 4X. I tried to flash new rom and reboot my phone on twrp. When the phone shut down nothing happens anymore just black screen. No fastboot or recovery mode. When I contact the phone to Windows pc it shows in device manager: Qualcomm HS-USB Diagnostics 900E (COM20). I have tried to flash new rom with QFIL and Miflash (tried to change the driver to Qualcomm HS-USB QDLoader 9008).
With QFIL the error is: Download Fail: Switch to EDL FailFailed to switch to Emergency Download mode.
With Miflash the error is: Cannot receive hello packet. MiFlash is trying to reset status!
Any suggestions?

Already tried that. Doesn't seem to change a thing.

Shouldn't it turn the driver to "Qualcomm HS-USB QDLoader 9008" after test point method?
This is what shows in command prompt:
C:\Windows\system32>adb reboot edl
error: device '(null)' not found
C:\Windows\system32>adb devices
List of devices attached
C:\Windows\system32>

After the test point method you will see a new "9008" device in the Device Manager.
Then all of the above commands will be completely irrelevant and useless.
In the 9008 mode use MiFlash, not QFIL/QPST, to reflash your phone.
Cheers!

The test points seems to change nothing. I think that after the " adb devices" command I should see my device listed but that is not the case and therefore impossible to flash rom. Somehow I should be able to change the "900E mode" to "9008 mode" without changing the driver manually and I think the test point method should do just that.

Here is video of what I have tried to do. If someone could point out what to do differently to get the flash work I would be very grateful.

Windows 10 will not accept the 9008 driver because the driversignature ist not signed from Microsoft.
If you will unbrick it with Windows 10 64bit look here: https://www.youtube.com/watch?v=2d8KEruHWPg
and here: https://www.maketecheasier.com/install-unsigned-drivers-windows10/

Had allready done that also. Gave it another try without success

Is the Qualcomm 9008 driver now installed?
Did you start the mi-flash tool with administrator privileges?

I installed the Qualcomm drivers but device manager still shows 900E driver unless I manually change it to 9008.
edit:
I finally succeeded with test point method. Now flashing. Im so grateful to you ConradB.

Thank you buddy .. Your 4 years old post help me to turn on my hard brick redmi 4x.
I don't know the actual reason of hard brick but The situation was my phone was in condition like
1. Possible to go in fastboot mode
2. When turning on there is only mi logo for fraction of second.
I tried test point method as described . It turned on in one attempt..I just want to add something. I face some issues after test point flashing . So I just flash miui again . Then It's working perfectly fine. After Test point flash check your battery. Maybe fully drained. Just charge it and turn it on..
I am posting this just for Information..

Xiaomi mi 8 hard brick!

hello, i have hard brick at my mi8 .
When i try to press the power button the phone doesn't boot, If i try to go into recovery mode it doesn't boot and same for fastboot mode.
The screen is unresponsive (no backlight) and it doesn't vibrate. When i connect the phone to my computer it is automatically recognized as Qualcomm HS-USB QDLoader 9008 (COM5) which correspond to the EDL mode (i think).
When try to flash any rom with miflash i get the error " cannot receive hello packet.
Can anyone help me ?:crying:

Likely you have too much power coming from your usb ports, use a usb hub such as this: https://www.amazon.com/BYEASY-Porta...jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
Now try Mi Flash again, make sure that the lock bootloader (which is checked by default) is unchecked.
Now it should work, be sure that you are using a fastboot rom and not a recovery rom. ( a recovery rom will not work)
Make sure that it is a fast boot for your device : If you have a global device here is a link with quite a few fastboot roms :https://c.mi.com/thread-1899815-1-0.html
If you still have trouble let me know, and tell me specifically how you arrived at your brick, I helped someone with this exact issue a couple of weeks ago, and I was going to link you to that thread. But i can't find it at the moment.

I get the same error " cannot receive hello packet" with hub USB.
MY xioami mi 8 is global version, i unlock the bootloader and make a downgrade with twrp to a older version of stable rom, and when the phone start ,its all ok and login my mi account, and the phone goes down and never more boot. Always in the pc i get qualcom port (edl mode) . Sorry for my bad english.:crying:

I think i need account with EDL authorization to flash any rom. And i can't found anyone to save me..

Try https://forum.xda-developers.com/mi-8/how-to/unbrick-mi8-edl-authorized-account-t3896677

Thank you .. i try this metod but no success

About s-unlock .. anyone knows if the service is online?

Maybe try this site : MOD EDIT: link removed
I dont have his name but one of the techs from this site is a frequent XDA user and supposedly legit.
In the end there is a risk of losing $12. Seems to be worth $12 to me.

I send message to this brother , and it's 40 dollars .. i'm thinking about
thanks for reply

Bricked 9T pro

I bricked my 9T pro when I mistakenly flashed it with 9T rom
Now the phone is recognized in device manager as QUALCOMM HS-USB QDLOADER 9008, It won't let me go into Fastboot mode to flash with Mitool.
screen is black all the time, no vibration while pressing power button.
Is there any solution for this, guys? I really need a phone to do my job and I'm kinda in a pickle right now :crying:

Download proper drivers of qualcomm from below link (all instructions are given)
https://xiaomifirmware.com/downloads/qualcomm-hs-usb-qdloader-9008/
Then use xiaomi tool v2
https://www.xiaomitool.com/V2/
It will detect your device

Thank you for the reply! I already had installed that drivers and the problem is, that Mitool V2 says No devices in fastbood mode found. I can't put my phone in fastboot mode :crying:

EDL mode
Put your phone in EDL mode and then flash the official ROM with mi flash tool (search on google how to put Mi 9T pro in EDL mode) do it with your own risk as it involves removal of back glass panel and shorting of 2 pins on the motherboard.

last night i got and update on my k20 pro 8gb 256 with QFKEUXM rom when i restart the phone it got hardbricked
My device is hard bricked, can't turn it on, access Fastboot or Recovery. It's also not charging, no LED and the power brick isn't getting warm. Bootloader-Unlocked , USB-Debugging disabled.
when i connected it to windows (but i didn't open it)
Windows is showing: Qualcomm HS-USB QDLoader 9008 (COM10)
I downloaded the latest Fastboot ROM for my device and region: raphael_eea_global_images_V12.0.5.0.QFKEUXM_
then tried to flash it via mi flash
MiFlash is recognizing as com10 the device and when i try to flash:
- start flash
- acessing the ROM (I think)
- ping target via firehose
then after 30 second says can't write time out device disconnected
i don't know what should i do i even payed 20$ for mi account auth via teamviewer i still got same error didn't get to auth part
the guy said your phone is dead impossible to fix it and told me even if you opened it and did testpoint it wouldn't help you (it's a hardware issue)
how can fix this issue sorry english is not my first language

Question Help needed. I think I bricked my phone...

I installed android 12 beta on my Mi 11 ultra. Did not like it and wanted to install global. Installed TWRP, wiped data and instead of rebooting in twrp, I tried to enter fastboot mode via adb. The phone screen turned black. Now it is not showing in ADB, not detected by Mi flash tool, not enetering fastboot mode and not entering recovery. When I connect it to computer, there is this connecting sound but soon it is followed by disconnecting sound. Not even getting the charging screen. In the device manager on Windows, there is this Qualcum HS-USB QDLoader 9008 (COM9) when the phone is connected via USB cable to PC.
Anyway to restore any firmware on it? It is a CN version, star, has bootloadder unlocked.
EDL time? Or even worse? Is it paperweight now?

EDL time I think.

Believe me, this is reassuring. I'm happy to settle on EDL instead of paperweight... For EDL does the phone need to be opened, back cover removed and then that magic short circuit or is there a way to get it done without opening the phone?

Don't worry. When mine was EDL flashed the guy asked me to download a specific miflash version that he had the link for and the ROM of choice to be flashed. I connected the phone to the PC, he connected, asked me to put it in to EDL mode ( he will explain if your not sure) and done his stuff using TeamViewer with control of my desktop. Once finished, just rebooted when asked, all done.

need mi auth to flash

How do you put the phone in EDL mode?

can you get your phone on fastboot?

Hold both vol up and down while powering up or adb, adb reboot edl or fastboot, fastboot oem edl . You will see edl drivers load on your PC.

Thank you guys for your replies. I got it fixed and now it is rocking again. If anybody faces the same issue, please see details below.
Diagnosis: EDL mode
Signs and problems: Completely dead phone. Black screen. None of the buttons or their combinations work. Volume down plus power, volume up plus power, Both volume buttons, All three buttons. None of these worked in this EDL mode. In fact, the only sign that this phone was "alive" was the Qualcomm driver showing in the device manager when the phone was connected to a PC. There was this yellow sign even on the Qualcomm driver and the official Xiaomi flash tool failed to detect the phone due to the Qualcomm driver malfunction. Got the Qualcomm driver working (the yellow sign on the driver name icon in device manager) by disabling windows driver signature check. After this the phone was detected by the official Xiaomi flash tool. When I tried to flash the official and stock CN ROM, it did not allow me and gave the error "you are not authorized to download". Took the phone to Xiaomi service, they refused as the phone was of another region. They did not know any unofficial paid solution. Took it to local technicians. They tried but failed (ultimate multi-tool, some other tool they called as "aqua" did not work.
Treatment: Searched online and found a YouTube channel (
). Paid USD 35 and got it flashed via TeamViewer. I just sat anxiously (praying that he must not be a scammer...). He did some magic and successfully flashed the phone with the original CN ROM with the boot loader unlocked. I then was able to install the global version via fastboot as usual.
Thanks again for the free support I got here. Obliged and stay blessed

I tried this method today and it wasn't successful. It appeared he flashed it with his auth code, but it still doesn't power on. I'm so bummed because DHL won't touch the phone for less than $151 (risk of it being sent back) because seller wants me to lie and say it's a gamepad when DHL has precautions on phones being sent back, etc. requiring importer certificates.
My phone was acting strange on 3rd day: wasn't detecting charging USB cable overnight, would only charge wirelessly. I manually rebooted a bunch of times, then it detected the USB charging and would charge. About that time I updated to Miui 13 OTA update (Chinese /EN Rom) and noticed it was rebooting randomly in my pocket asking for PIN (not getting notifications) . Again got no USB charging through cable.
I was doing a bunch of vol up/down and Power and rebooted into safe mood. Rebooted again after things were 'ok' and little while later, the phone was OFF and never came back on again.
Did I put it into EDL and brick it this way? I Never flashed anything through USB until I tried the 35eur paid service dude.

Happy to see that is being fixed.

Wish it had fixed mine. Unfortunately, it didn't . Was refunded
